To aZZ whom 2'73 may concern:

Be known that I, DYER T. Knnnnron, a citizen of the United States, residing at li orcester, in tlie county of \Vorcester and State of, Massachusetts, have invented cer- In new and isei'ul improvements in Cardhines, or which the following specification. This invention relates to card stringing machines more particularly adapted for use in drawing the suspending cord through holes in calendar cards or the like, and the object of this invention is to provide simple and effective means whereby when the string or cord is drawn from a spool or other supply package it may be readily positioned over the holes in the card, means being provided for then severing and drawing its ends through the holes in the card automatically, whereby these ends may be subsequently tied together to provide a loop at the top of the cord by which the same, with its attached calendar, may be hung upon a nail or other support.

VJith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings 2- Figure l is a top view of my improved card-stringing machine.

Figure 2 is a side elevation of the same, showing the connection between the draw rods and the treadle; also the connection between the treadle and the cutters as broken.

Figure 3 is a side elevation illustrating the treadle and the two connecting rods pivotally secured thereto.

Figure & is an enlarged edge view through the card-suppporting table and one of the draw-nods, showing the cord engaging hooks extending upwardly through the holes in the card.

Figure 5 is a detail. illustrating the cam for operating the cord-cutting shears.

Figure 6 is a perspective view showing a calendar card having spaced-apart holes through which the ends of the cord have been drawn.

Ordinarily cards of the calendar type-are strung by hand, which is a slow operation even by skilled operators, and the cord used is generally out too long and much is wasted SACHUSETTS, ASSIGNOB TO LIVEEMOBE & HOIDE lSLA'riD li CORPORATION OF RHODE smonrnn.

which where By the use of my improvedmachine this difficulty is obviated as the cord is drawn out to a gauge and cut to exactly the-required length then it is automatically drawn by a single operation through both otthe holes in the card ready to be subsequently knotted together, and the following is a detailed description of one means by which this result may be accomplished With reference to the drawings, 10 designates the table which is supported on legs or standards 9 and on which a calendar card 11 or other card to be strung, is supported. This table is provided with a transversely adjustable gauge 12 and a longitudinally-adjustable gauge 18 to assist in positioning the calendar so that its holes 14 which are of a definite or standard distance apart will register with the holes 15 in the table of my improved machine.

Near the left end of the table I have mounted brackets 16 in which spool or sup ply package of cord or ribbon 17, with which the card is strung, is rotatably mounted, and between this package and the holes 15 in the table, i have mounted a-pair of cutters 18 preferably in the form ofshears for cutting the cord at its required length after it has been drawn over the card to be strung. One of the blades of these shears is fixed as at 19, see Figure 5, while the other blade is pivoted at 2]. and. is normally pressed into open position by the spring 22.

In order to swing this movable blade upon the fixed blade, I have mounted a roll' 23 on the lower. end thereof to be engaged by the cam 2-41- on the bar 28 which slides vertically in the guides 25, its lower end being connected at 26 to the treadle 27 whereby the last upward movement of this end of the treadle causes the shears to close and sever the cord.

To work vertically in the holes 15 through the table 10, I have mounted a pair of hooks 29 formed of wire or other suitable material, each being secured to the spaced apart ends of the draw-rods 30 which are preferably connected at their lower ends by the bridge 51 forming a U-shaped member as illustrated in Figure 2, mounted to work in the bearing block 37. These rods are connected byan eye member 32 to the upper end of the connecting rod 83, the lower end of this conis a considerable item particularly high-priced silk cord is employed;

' card.

nection being hingedly joined at 34: to the treadle 27, which treadle itself is shown as being pivotally mounted at 35 in the brackets 36.

In operating my improved card-stringing machine, I first position a card 11 against the guides 12 and 13 so as to bring its holes 1% into position to register with holes 15 in the table. It then engage, by hand, the end of the cord 38 which extends through the eye 39 and'normally lies where severed by the cutters l8, and draw this end to the right. until it abuts 40. is the hooks at this time are raised above the table and extend through the holes in the card, the shank portions 41 of the hooks serve as a guide or stop against which the cord is positioned from the front thereby centering this cord over the holes 1% in the card. The operator next moves the outer end of the foot treadle 27 upwardly slightly causing the cam portion 24: of the rod 28 to engage and close the shears severing the cord at exactly the desired length. The outer end of the foot treadle is now moved downwardly causing the hooks 29 to engage the two bights of the cord above the holes in the As these hooks now descend they draw the free ends of the cord through the holes in the card into the position illustrated in Figure 6.

The card is now removed, another positioned upon the table and the cycle of operations repeated as fast as the cards can be positioned and removed from the table.

It will be noted that the movement of the treadle performs two functions, first, it operates the shears to sever the cord; and secend, it draws the ends of the cord throng, the eyes or holes in the card.

After the cards have been strung the ends 42 of the cord are tied together thus providing a loop by which the card or calendar may be supported. My improved cardstringing machine is extremely simple and against the length gauge 1 practical in its operation and by its use calendars or other cards may be strung very rapidly and that without wasting any of the expensive silk cord used for this purpose.

The foregoing description is directed solely towards the construction illustrated,

but I desire it to be understood that I reserve the privilege of restoring to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In a card-stringing machine, a cardsupport, a string cutter, a pair of string-engaging members adapted to be moved relatively to said support to extend through holes in the card to engage the string on the opposite side thereof, and manually operable means for moving the string-engaging members to draw the string ends through the card holes by a movement of said members in one direction and for moving said cutter tosever the string when said members are moved in the opposite direction to string-receiving position.

2. In a card-stringing machine, acardsupport having spaced openings therein, a string cutter, a cam member slidably mounted to operate said cutter, a guide block beneath said support with spaced holes therein registering with said openings, a pair of string-engaging members slidable in said holes and through said openings, a manually operable fulcrumed treadle lever, links operably connecting said string-engaging members and said cam member whereby a movement of said lever to cause said engaging members to move to string-receiving position causes said cam to operate the cutter and sever the string. 7

In testimony whereof I affix my signa ture.
